My job is delivering auto parts, and my company has a small fleet of terrible little hatchbacks. Someone less terrible than others, and seniority gets you preferred cars. “My” car is a 2015 Yaris. I say mine because I drive it Monday to Friday, Saturday is the only day someone else drives it. I sometimes leave empty coffee cups in the car when it slips my mind, but overall I keep my car the cleanest out of everyone. Every Monday, I come back to radio presets changed, my pens stolen, used tissues and random garbage on the floor and seats, my box in the back gone, which I keep to put parts in. There’s usually a new door ding or scuffed bumper too. It drives me up the fucking wall.

Why is it so hard for people to leave things as they found them? Yesterday I went home early, at about 1pm. Someone felt the need to switch to my car for not even half the day, apparently. I already find that selfish, changing someone’s mirrors and seating position just so you can have a nicer car for a few hours. But they also changed all my radio presets, and turned the car off with the volume absolutely cranked. I see that as just being an inconsiderate dick. What do you think, am I being unreasonable in my expectations when it comes to semi-shared work vehicles?
